General Information
Blower coil units are draw-thru air handlers for cooling load
conditions of 400–4000 cfm. Units are available in
horizontal (model BCHE) and vertical (model BCVE)
configurations. Horizontal units are typically ceiling
suspended via threaded rods.
Lugs are provided on all four corners to secure the rods.
Horizontal units can also be floor mounted. Vertical units
are typically floor mounted. They have a side inlet for easy
duct connection, and do not require a field fabricated inlet
plenum. Vertical units ship in either one piece (size 24-60)
or two pieces (size 72-120). Horizontal and Vertical
Accessory sections ship separate from the main unit.
Basic unit components consist of a coil, condensate drain
pan, filter, duct collars, one fan wheel, and an electronically
commutated motor (ECM).
Four-row, six-row or eight-row main coils are available for
either hydronic cooling or heating. Three, four, or six-row
direct expansion (DX) coils are also available for cooling.
An optional one-row or two-row heating coil is available
factory-installed in either the preheat or reheat position.
All units have a bolt on flat filter frame for one or two two-
inch filters. An optional angle filter box (two inch only),
mixing box, bottom filter access box, or combination angle
filter mixing box is available. In addition, all units are
available with valve kit. The valve kit consists of a control
valve (Pressure Independent Control (PIC) valve available
as an option), a circuit setter, and a strainer.
Direct-drive motors range from 1/2 to 5 horsepower in a
wide range of voltages. All motors have internal current
overload protection, permanently sealed ball bearings, and
rubber grommets on the mounting brackets to reduce noise
and vibration transmission.
Motors come factory programmed for specific job
requirements or can be programmed based on
standardized motor speeds. Field adjustment of motor
speeds can be adjusted through the VelociTach™ motor
control board. This enables the unit to be easily balanced
for changes to design static pressures. Refer to the original
sales order and the motor control board label on the unit for
the programmed motor speed. Several factory installed and
tested control options are available.
